    text
    copied!<p>I have a page with a radiobuttonlist and textarea. data is displayed dynamically within the textarea based on the user's selection. i also set up a OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged" to create a url that will allow users to reference their article (radio button selection). </p> <p>everything works except for cutting and pasting the created url (i.e. <a href="http://test.com/test.aspx?selected=3" rel="nofollow">http://test.com/test.aspx?selected=3</a>) into a new browser. the code keeps assigning the radiobuttonlist1.selectedindex to -1.</p> <p>so here's what i'm seeing in debug mode</p> <p><strong>Case 1</strong> when i cut and past the url in to a new browser <a href="http://test.com/test.aspx?selected=1" rel="nofollow">http://test.com/test.aspx?selected=1</a>, at the end of the page_load method code RadioButtonList1.SelectedIndex is equal to = -1. for some reason it's' not assigning the selectindex correctly.</p> <p><strong>Case 2</strong> when i select a radio button within the web page i launched, it skips the page_load code because <strong>post back is true</strong>. then creates a url within the RadioButtonList1_SelectedIndexChanged. then runs through the on page load method and hold the correct RadioButtonList1.SelectedIndex value at the end. </p> <p><strong>Case 3</strong> when i select a link within the webpage launched that is using pointing to <a href="http://test.com/test.aspx?selected=2" rel="nofollow">http://test.com/test.aspx?selected=2</a>, postback is false so it loops though the page_load code and successfully hold the correct RadioButtonList1.SelectedIndex value at the end.</p> <pre><code>protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { int selected; if (Request.QueryString["selected"] != null) { if (int.TryParse(Request.QueryString["selected"], out selected)) { RadioButtonList1.SelectedIndex = selected; RadioButtonList1.DataBind(); } } else { int firstart = 0; RadioButtonList1.SelectedIndex = firstart; } } } protected void SqlDataSource2_Selecting(object sender, SqlDataSourceSelectingEventArgs e) { } protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e) { try{ e.Command.Parameters["@URL_FK"].Value = Session["URL_PK"]; } catch (Exception ex) { } } protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e) { string strRedirect; strRedirect = "test.aspx?selected=" + RadioButtonList1.SelectedIndex; Response.Redirect(strRedirect); } } </code></pre>
